From: Yu Kuai <yukuai3@xxxxxxxxxx>
Hi all,
this series tries to fix the delayed holder tracking that is only used by
dm by moving it into dm, where we can track the lifetimes much better.
v2 is from Christoph, here I send v3 with some additional fixes.
Changes since v2:
- add patch 5 8 and 10 to this series.
- rewrite last cleanup patch from v2.
Changes since v1:
- don't blow away ->bd_holder_dir in del_gendisk or add_disk failure
as the holder unregistration references it
- add an extra cleanup patch
Christoph Hellwig (6):
block: clear ->slave_dir when dropping the main slave_dir reference
dm: remove free_table_devices
dm: cleanup open_table_device
dm: cleanup close_table_device
dm: track per-add_disk holder relations in DM
block: remove delayed holder registration
Yu Kuai (4):
dm: make sure create and remove dm device won't race with open and
close table
block: fix use after free for bd_holder_dir
block: store the holder kobject in bd_holder_disk
block: don't allow a disk link holder to itself
